1. Catalyst Look at 6.2.Pollution Facts and 6.2.Cleanest Cities Name 3 of the cleanest cities for year-round pollution and ozone pollution. Also name the 3 dirtiest cities. What do you notice about where these cities are?

2. What city has the most pollution? Which city has the least pollution?

3. Examine the Data What similarities do you notice about the data? What differences do you notice?

4. Environmental Justice Environmental Justice is the study of how and why traditionally underrepresented communities bare a disproportionate burden of environmental hazards Communities with a high minority population typically live in more polluted areas.

6. Environmental Justice Reading Annotate and answer the questions with the article

7. Health Impacts of Living in Pollution Increased chances of: – Lung Cancer – Respiratory Infections – Asthma This leads to countless missed days of school and lost hours at work

8. Group Proposal With your group, create a proposal that: – Outlines an environmental problem that you see you in your community – Why this is a problem – How this problem should be fixed

9. UNIT 6 THEME – GAS LAWS AND ENVIRONMENTAL JUSTICE

11. How to Get An Egg Into a Bottle

12. Justify – TPS Why did the egg get sucked into the bottle? Draw a picture if it helps you explain.

13. LECTURE 6.2 – GASES, PRESSURE, AND DIFFUSION

14. Today’s Learning Targets LT 6.1 – I can explain how pressure is created through the collisions of molecules with a surface. LT 6.2 – I can discuss how the diffusion of a gas through a space is the result of the random motion of a gas molecule

15. What are gases?

16. I. Gases One of three states of matter. Move in constant random motion. They fill an entire container and are spread very far apart.

18. What is pressure?

19. I. Pressure The collisions of gas molecules with a surface are what creates pressure. Pressure is the amount of force that is exerted per unit of area.

21. II. Pressure Has Many Units Pressure is measured with a barometer and it is measured in numerous units. The units of pressure are atm, bar, mm Hg, Pa, and torr.

22. The Sad Story of My First Love

23. Justify – TPS Why did the people closer to the air canister smell it sooner then the people further away from it?

24. What is diffusion?

25. I. Diffusion Diffusion is the movement of particles from regions of higher density to regions of lower density. Because gases are constantly in random motion, they spread out from one another quickly. This random motion of gases is what explains the process of diffusion

27. You’ve Seen Diffusion Before!

28. Draw Something – Make Wikispace Memorable

29. Draw Something Gas Pressure Diffusion A heavy gas diffuses slower than a light gas Units of Pressure
